In today's Globe.
"Since a body was never found, no one can be certain what happened to Harris Harper. But the consensus, said Mrs. Tippett, is that it was suicide from depression. A few months before he disappeared, she said, he had suffered a nervous breakdown. He then tried to return to his job at the school, but they gave him some tests to mark “and it was all marked wrong and he couldn’t conduct school.”
That may have been the clincher. She recalled that “he was last seen by a nurse and they think that he walked down Main Street, turned left and went past Eaton’s to the bridge and jumped in the river. The tide took him out.” A large search party, which included Mrs. Tippett’s husband, came up empty-handed.
Harris Harper, she recalled, was a nice-looking man, polite but firm. A military buff, he insisted that teachers put classes through “physical drills,” a daily exercise regime. He had a small speech impediment, and pronounced proof as “poof”; the teachers used to mock him for it and refer to him as “Poof Harper.” The memory still rankles Mrs. Tippett."

Reading between the lines, it seems likely that Harper's granddad may have committed suicide over insinuations that he was gay (it is unlikely that the insult "Poof Harper" was motivated by a speech impediment, since it is a well known slang derogatory term for homosexual). This occurred in 1950 after all.
Given that family background, you might think Harper would be in favor of openness and tolerance for gays. But apparently he is not willing to stand up to the homophobes in his party.
